Answer / umer bhat

Any attribute (or set of attributes) that uniquely
identifies a row in a table is a candidate key for primary
key. Such an attribute is called a candidate key. One of
the candidate keys is chosen to be the primary key, based
on the familarity and greater usage. Any attribute that is
a candidate key for the primary key but is not the primary
key is called the Alternate key. When the key uniquely
identifies the row of the table is made than one attribute,
it is called a Composite key.

Answer / burhan mughal

All candidate keys which are not chosen as "primary key"
are Alternate keys. The key which uniquely identify the
rows of the table and which is made up of more than one
attribute is called Composite key. Generally a candidate
key becomes the primary key of the table. If the table has
more than one candidate key, one of them will become the
primary key, and the rest are called alternate keys.

Answer / bidut karki

Candidate key is a key that works as to uniquely define a record by combination of all attribute inside a table.
However, A candidate key that is not a primary key is called an Alternate key.

The factorial of a nonnegative integer n is written n! (pronounced “n factorial”) and is defined as follows: n! = n · (n - 1) · (n - 2) · … · 1 (for values of n greater than to 1) and n! = 1 (for n = 0 or n = 1). For example, 5! = 5 · 4 · 3 · 2 · 1, which is 120. Use while structures in each of the following: a) Write a program that reads a nonnegative integer and computes and prints its factorial. Use the following function prototype to calculate factorial: int myFactorial(int n); b) Write a program that estimates the value of the mathematical constant e by using the formula: Use the following function prototype to calculate e: double myE( ); Hint: Use an accuracy of 10 terms. c) Write a program that computes the value of ex by using the formula Use the following function prototype to calculate e: double myEx(int x);
